e1408ts : reverse kinker as adult variably Egl; L1 moves well; variable failures in postembryonic migration of Pn nuclei into ventral cord and (some alleles) embryonic migrations of hyp-7 hypodermal nuclei; all alleles are ts for Pn defect non-ts for hyp-7 defect; unmigrated Pn nuclei mostly fail to divide; adult male phenotype variable some can mate at 25x all can mate at 15x. ES3 ME3 (15x). NA11 (n331amber ts; e1409amber ts (suppressible only for hyp-7 defect)).

Studies in elegans have contributed much to the knowledge of SUN-KASH protein complexes which link components of the nucleus to the cytoplasm; KASH domain proteins in elegans are involved in nuclear positioning and migration; the family of mammalian KASH (klarsicht, ANC-1 and Syne) domain proteins include Nesprin-1/SYNE1, Nesprin-2/SYNE2, Nesprin-3/SYNE3 and Nesprin-4/SYNE4) that encode at least 12 isoforms, by alternative transcription and splicing; most KASH domain proteins do not share primary sequence homology outside of their KASH domain; mutations in SYNE1, similar to those in LMNA/Lamin, cause laminopathic diseases like Emery-Dreifuss muscular dystrophy (EDMD) and Spinocerebellar ataxia.
